A word of counsel

The most common error on this tariff line is treating it as a straightforward organic chemical without screening the specific end-use against the Schedule to the Insecticides Act, 1968. A consignment cleared without CIB&RC registration and permit — where the substance is in fact scheduled — is liable to seizure and prosecution at port; the CIB&RC port restriction under Rule 45 of the Insecticides Rules, 1971 compounds this exposure because even a correctly licensed consignment arriving at an unnotified port cannot be cleared. Additionally, where quantities of hazardous substances exceed specified thresholds, an insurance policy under the Public Liability Insurance Act, 1991 is mandatory per S.O. 227(E) dated 24-03-1992.
